Look at the C41 formula published here on APUG. It is nearly correct. Your pH is far too high. The correct pH is about 10.2 or thereabouts. The temperature is supposed to be 38.x degrees C (I forget the exact equivalence to 100F). So, there are so many things wrong with your process I hardly know what to suspect first. Try to replicate C41 exactly first and then make variations.

My Intention is to get my own negatives, with my own saturation and color density.

I solved so much, by many many tries but get stuck at the magenta cast.

But to understand why:

My greenish negatives means, that the cyan dye layer and the magenta layer is not dense enough (caused by wrong developement)? So I get redish images? And I have to find a way to get a denser cyan layer?

Or am I completely wrong?

The free on-line (PDF) part 5 Using Kodak Flexicolor Chemical "5 Process monitoring and troubleshooting" (Z131_05) should help you diagnose most shifts as temp/pH/time vary from spec. for c41 chemistries. The response of each of 3 color layers is plotted in graphs starting at page 5-29. With them you can see the relationship that varying each parameter has on each color layer. Most useful in figuring what/where/howmuch you want to start modifying when working with "known" chemistry. If your working at weird temps, like 25C and non-standard chemsitry, you're kind of on your own to determine each effect. I suspect the information in the manual will still be somewhat useful. Don't have the link handy, but it's easy to find on-line.
